Modelling green Ammonia and Methanol in 2050. It will be expensive

September 9, 2022 by Schalk Cloete

Schalk Cloete starts by explaining that it is unrealistic to expect clean electrification to carry the main burden of energy supply. Even a fast roll out will be constrained by a range of infrastructure and cost limitations. Hence our continued dependence on fuels, with their high energy density and ease of transport. Those fuels will have to be made clean, so he summarises his co-authored papers that model the cost of green and blue ammonia and … [Read more...]

Clean Turquoise Hydrogen: a pathway to commercial readiness

July 22, 2022 by Schalk Cloete

Whereas blue hydrogen from methane produces CO2, the by-product of turquoise hydrogen is pure carbon. The obvious advantage is you can make your hydrogen without the need for expensive new infrastructure to transport and store any CO2. Turquoise hydrogen is only at the start-up phase, so Schalk Cloete summarises his co-authored paper that looks at various scenarios to estimate the cost of producing the hydrogen (using molten salt pyrolysis) and, … [Read more...]

46% of Buildings “Embodied Carbon” can be slashed at little to no cost

April 20, 2022 by John Matson and Rebecca Esau

Buildings and their construction account for around 40% of all carbon emissions today. Half those emissions come from the construction alone, so buildings successfully powered by clean energy won’t come close to fixing the whole problem. John Matson and Rebecca Esau at RMI describe how industry leaders are creating the tools to measure and gather data on the “embodied carbon” in building materials (concrete, rebar, glazing, insulation, other … [Read more...]

World’s biggest Carbon Capture project: Shute Creek’s “sell or vent” business model isn’t working

April 11, 2022 by Bruce Robertson and Milad Mousavian

ExxonMobil’s Shute Creek CCUS facility is the world’s largest carbon capture project. But since its launch in the 1980s half of that CO2 has been vented into the atmosphere, with most of the rest sold for pumping it underground to push out more oil from depleted wells (called Enhanced Oil Recovery). Only 3% has been sequestered underground, explain Bruce Robertson and Milad Mousavian at IEEFA, following their study based on publicly available … [Read more...]

Imagine it’s 2030 and net-zero is on track. How did we do it?

January 18, 2022 by Tim Buckley

Imagine it’s 2030. The energy transition is on track and net-zero goals are entrenched across the global economy. How did we get there? Tim Buckley at IEEFA imagines it for us and sends us a postcard from the future. Writing in the past tense, he flags actual events and policies happening today to “remember” the major changes that took place to achieve it. Weather-related disasters compelled governments to act, recognising – apart from the … [Read more...]

Can Carbon Offset loopholes be fixed with better evaluation and rules?

December 14, 2021 by Meredith Fowlie

Carbon offset programmes rightly get a lot of criticism. There’s plenty of evidence of offsets not delivering all the GHG emissions reductions they are credited for. Though still on the international agenda, should they be ditched? Or can they be improved with better analysis and evaluation, and making that a pre-condition for creating carbon offset credits, asks Meredith Fowlie at the Energy Institute at Haas. She starts by looking at those … [Read more...]

Renewed interest in Carbon Capture strategies for net-zero: targets, obstacles, costs, priorities

November 10, 2021 by Martina Lyons

Martina Lyons at IRENA picks out the highlights of their new report “Reaching Zero with Renewables: Capturing Carbon”. Carbon capture is going to be expensive, so should be focussed on hard-to-abate industrial sectors, as well as bioenergy plants. Lyons breaks down the target carbon capture volumes, costs and the investments required, as well as looking at the consequences of different strategies and carbon prices. Scaling up this technology, … [Read more...]

Climate Finance: the loopholes that are causing greenwashing

November 4, 2021 by Meredith Fowlie

How do you know when an investment is truly “green”? Whether companies and fund managers monitor themselves or are externally policed, the correct rules need to be identified. And then it gets harder. Clearly defining and then measuring carbon footprints is a bigger challenge, explains Meredith Fowlie at UC Berkeley’s Energy Institute at Haas. She draws parallels with food nutrition labelling rules. But whereas counting the calories in a food … [Read more...]

Will COP26 set right the booming Carbon Offset Market

November 3, 2021 by Kerstine Appunn

Carbon offsetting is when a company, rather than cut its own emissions, pays someone else somewhere else to cut their emissions. It has always been controversial because it has two main problems. Buying carbon credits means you aren’t putting the effort in to cut emissions yourself. And the risk of double-counting: when the company reports it has cut emissions, and so does the “someone else”. A third problem exists too: measuring whether the … [Read more...]

Only Carbon Removal can make Germany’s new climate goal a reality

September 6, 2021 by Simon Göss and Hendrik Schuldt

Germany can’t hit its emissions targets without significant carbon dioxide removal (CRD), explain Simon Göss and Hendrik Schuldt at cr.hub. Clean energy and energy efficiency won’t do it alone. Policymakers have grasped that hard-to-abate sectors (industry, agriculture, buildings, transport) will struggle to deliver the reductions needed. Meanwhile, the climate disasters (floods, wildfires, etc.) that have cost lives this year are piling on … [Read more...]

What if Carbon Capture fails? Modelling the consequences and solutions

July 5, 2021 by Neil Grant and Ajay Gambhir

Most policy scenarios being used by governments include carbon capture as a vital tool to reduce emissions. Though it’s far from proven at scale, models assume that between 2030 and 2050 carbon dioxide removal (CDR) will get its act together and deliver on its part in the net-zero puzzle. Assuming that will happen, burning fossil fuels can continue for longer. But Neil Grant and Ajay Gambhir at Imperial College London, writing for Carbon Brief, … [Read more...]

CCS: Identifying the best underground locations for storing CO2 can take 10 years, so let’s start now

April 23, 2021 by Raimund Malischek and Samantha McCulloch

Underground geological formations have more space to store CO2 than we’ll ever need, by orders of magnitude. But the process of assessing the best locations can take up to ten years, so that work needs to start now, say Raimund Malischek and Samantha McCulloch at the IEA. The main constraints are technical (which porous rock formations absorb CO2 most easily, etc.), while the displacement of land use and public acceptance must also be considered. … [Read more...]

EEMPA solvent and CO2 mineralisation can take us one step closer to our carbon capture goals

March 30, 2021 by James Conca

If the models are correct that global carbon emissions will keep rising until at least 2040 then carbon capture and storage (CCS) is essential. And most of the vast amounts of CO2 we must capture won’t be “utilised” as it’s more than we can possibly use. So storage is an essential part of the equation, explains Jim Conca. He scopes out the problem before looking at two innovations that can bring costs down and bring the technology one step closer … [Read more...]

Carbon Border Adjustments: can the EU create a mechanism that is fair?

February 22, 2021 by Michel Colombier

The proposed EU carbon border adjustment mechanism (CBAM) is meant to control imports of high-carbon goods from places that are not bound by Europe’s rising de-carbonisation rules. The obvious targets are commodities like steel, aluminium and cement. But it could be extended to all EU imports, including agricultural products. Michel Colombier at IDDRI warns that the EU is in danger of not listening nearly enough to its trading partners. He … [Read more...]

“Electro-swing cell” captures CO2 direct from the air

September 2, 2020 by Nancy Stauffer

The problem with capturing carbon from a power plant is that the CCS system is itself huge, expensive, consumes a lot of energy, and only works on exhaust streams with high concentrations of CO2. What’s more, to meet global CO2 targets, total atmospheric CO2 has to be reduced, not just held at today’s concentrations by capturing new emissions alone. Writing for MIT, Nancy Stauffer explains how researchers there are piloting an “electro-swing … [Read more...]
